With great interest, I read the letter to the editor by Professor Rolf-Markus Szeimies recently published in JEADV(3) .

(2012)(1) , Professor Szeimies commented that he had detected a statistically significant imbalance in actinic keratosis (AK) lesion severity at baseline between the two active treatment arms.
